Description
Technical field
The utility model belongs to Geotechnical Engineering anchoring field, and in particular to a kind of novel anchor rod multistage allows pressure device.
Background technology
Suspension roof support refers to be adopted in the construction of the earth's surface engineering and tunnel, stope etc. such as side slope, ground deep basal pit underground chamber
A kind of its support reinforcement mode.Be made roofbolt with metalwork, wooden piece, polymer member or other materials, squeeze into earth's surface rock mass or
In the pre-drilled hole of chamber surrounding rock body, using its head, the special tectonic of the body of rod and afterbody supporting plate, or depend on and cohere work
Suspension effectiveness, combination beam effect, reinforcing effect are produced with country rock and rock mass stability are combined together, to reach the mesh of supporting
's.With the increase of tunnel buried depth, stress is significantly increased, and roadway surrounding rock stress increases.In the big change high of buried soft rock, crustal stress
In shape tunnel, because surrouding rock deformation is larger, and anchor pole elongation percentage is not enough, so anchor pole is easy to be pulled off.Therefore, in large deformation
In roadway support, anchor pole need to generally arrange in pairs or groups allow pressure component carry out supporting.
However, the pressure-relieving achor bar in existing bolt support technology builds and still suffers from some problems, it is mainly manifested in：（1）Allow
Not enough, though serve certain pressure that allows acting on, final anchor pole is still pulled off and loses pressure stroke because surrouding rock deformation is excessive
Remove support action；（2）Allow pressure device makes pressure conformability single, and such as use pallet, damping plug allows pressure component, allows pressure scope
Small, it is difficult to adapt to deep wall rock stress complicated and changeable, strain field, there is the protective effect to anchor pole limitation to limit.Based on upper
Technical problem is stated, existing pressure-relieving achor bar needs further improvement.
The content of the invention
The purpose of this utility model is directed to the above mentioned problem of prior art presence, there is provided a kind of novel anchor rod multistage allows pressure
Device, its technical solution is：A kind of novel anchor rod multistage allows pressure device, it is characterised in that：Including pallet, upper padding plate, under
Backing plate, spring assembly, nut；Described pallet, between nut and upper padding plate；Described upper padding plate and lower bolster, is circle
Shape thin sheet form, described upper and lower backing plate center is provided with circular cavity, and anchor pole can be passed through from the cavity；The spring assembly,
By one-level allow pressing spring, two grades allow pressing spring, three-level to allow pressing spring to constitute, one-level allows pressing spring highly to allow pressing spring more than two grades
Highly, two grades allow pressing spring height to allow pressing spring highly more than three-level, and one-level allows pressing spring to be made up of some brute springs, is located at
Outmost turns position, two grades allow pressing spring to be made up of some brute springs, in most mesosphere position, if three-level allows pressing spring by dry strength bullet
Spring is constituted, in the most inner ring position.
Used as a kind of preferred scheme, described upper padding plate lower end is provided with the recessed of one group of circumferentially some alternate uniform arrangement
Groove, makes pressing spring corresponding with one-level, and described lower bolster upper end is provided with three groups of grooves of circumferentially some alternate uniform arrangements,
Allowed with one-level respectively pressing spring, two grades allow pressing spring, three-level to make pressing spring corresponding.
Used as a kind of preferred scheme, described spring assembly is located between upper padding plate and lower bolster, and one-level allows on pressing spring
Lower two ends are adhesively secured in the corresponding recesses of upper padding plate and lower bolster by strength adhesive, as rockbolt stress deformation is continuous
Increase, upper padding plate constantly pushes, compress successively one-level allow pressing spring, two grades allow pressing spring, three-level to allow pressing spring.
The utility model has advantages below compared with prior art：
In the utility model anchor pole by upper padding plate by suffered stress special delivery to pressing spring component is allowed, allow pressing spring for strongly
Spring, as stress is continued to increase, the three-level in spring assembly allows pressing spring to compress successively, and reaction force increases step by step suffered by anchor pole
Plus, while realizing allowing step by step pressure, allow the effect of pressure with big stroke.
